The palm oil industry has developed rapidly, both in terms of cultivation and
development of its derivative products. Palm oil is classified as a crop that requires
extra care to obtain the optimal productivity. The study for understanding
characteristics of oil palm under various conditions is feasible in order to optimize the
productivity. Identification of bio-electrical properties of plants will provide a basic
knowledge of molecular and ionic behaviors which contained in the plant organs,
including fruit bunches and the fruit. This study provides a preliminary study of the
electrical properties of oil palm bunches and fruits. A low direct current (DC) voltage
injection treatment, ~ 10V, was applied to investigate the characteristics of responded
voltage, resistance, internal capacitance, and power dissipation in bunches and the fruit.
The results show that oil palm fruit bunches quickly recover the charge polarization that
occurs during the injection of the applied electric voltage. Electrical voltage injection
produces a polarization of charge on the cell wall of oil palm bunch which is indicated
by the presence of ~ 6 μA ion currents. This polarization is temporary and disappears
immediately about 5 minutes after the voltage source is disconnected. Investigation of
the responded voltage on oil palm fruits with different levels of maturity, namely
under-ripe, ripe and over-ripe, shows a fairly clear difference. The over-ripe fruit gives
the highest voltage, around 1.8 - 2.1 V. While the ripen fruit produces the lowest
voltage. However, the energy dissipation of the ripen fruit is greater than the other
fruits, which is 39.48 mJ for 110 seconds of the injection. This responded voltage tends
to increase by increasing the level of maturity, but decreasing for the over ripe fruit
which has fallen and started to dry out.
